摘　　要：以变速机组的运行特点为切入点,分析其在抽水蓄能建设方面的优势,并通过有无选取变速机组进行工程设计对比分析,旨在从机组建设可行性、能量指标、经济指标等方面例证变速机组对我国抽水蓄能电站规划和建设的积极影响,为推动变速机组在我国的建设进程提供决策依据。Based on the operation characteristics of variable speed unit, the advantages of variable speed unit in the construction of pumped storage are analyzed. Through the comparison and analysis of engineering design with and without variable speed units, the impacts of variable speed unit on construction feasibility, energy index and economic index on pumped-storage power stations in China are analyzed. The results show that the variable speed unit has a positive impact on the layout and construction of pumped storage power station in China. The research results also provide decision-making basis for the construction process of variable speed unit in China.
